この節ではサンプラーというものを作成します。
シェーダにおいてテクスチャの特定の位置の色を取ってくる、という操作をテクスチャサンプリングと呼ぶことを6章の最初で説明しました。ところで、テクスチャのピクセルとピクセルの間あたりの色をサンプルした場合はどのような色になるのでしょうか？
実はこの時の処理には複数の方法があります。
よく使われるものとしては、単にもっとも距離の近いピクセルの色を取ってくる(つまり見た目としてはドット絵のようになる)ニアレストネイバー法、また隣り合うピクセルを線形補間する線形補間法(バイリニア法)などのアルゴリズムがあります。
こうした処理はGPUで勝手に行われるため、自分でアルゴリズムを実装する必要はないのですが、どのアルゴリズムを使うのかはGPUに伝える必要があります。
サンプリングの技術はこれだけに留まらず、他にもミップマップ、異方性サンプリングなどといったものが存在します。こうした技術のどれをどう使うのかによって描画結果の美麗さが違ったり処理の重さが違ったりするため、サンプリングというのは単に「色を取ってくる」というだけのことでありながら様々なオプションの設定が必要なのです。
これらの設定情報を取りまとめるためのオブジェクトがサンプラーです。

vk::SamplerCreateInfo samplerCreateInfo;
samplerCreateInfo.magFilter = vk::Filter::eLinear;
samplerCreateInfo.minFilter = vk::Filter::eLinear;
samplerCreateInfo.addressModeU = vk::SamplerAddressMode::eRepeat;
samplerCreateInfo.addressModeV = vk::SamplerAddressMode::eRepeat;
samplerCreateInfo.addressModeW = vk::SamplerAddressMode::eRepeat;
samplerCreateInfo.anisotropyEnable = false;
samplerCreateInfo.maxAnisotropy = 1.0f;
samplerCreateInfo.borderColor = vk::BorderColor::eIntOpaqueBlack;
samplerCreateInfo.unnormalizedCoordinates = false;
samplerCreateInfo.compareEnable = false;
samplerCreateInfo.compareOp = vk::CompareOp::eAlways;
samplerCreateInfo.mipmapMode = vk::SamplerMipmapMode::eLinear;
samplerCreateInfo.mipLodBias = 0.0f;
samplerCreateInfo.minLod = 0.0f;
samplerCreateInfo.maxLod = 0.0f;
vk::UniqueSampler sampler = device->createSamplerUnique(samplerCreateInfo);
色々設定はありますが、ひとまず注目すべきはmagFilter・minFilterあたりでしょうか。 これらは最初に説明したような補間用アルゴリズムを指定するためのものです。ニアレストネイバー法を表すvk::Filter::eNearest、線型補間法を表すvk::Filter::eLinearなどが指定できます。 2つあるのはそれぞれ、画像の拡大時(magnification)・縮小時(minification)に対応しています。
addressModeU, addressModeV, addressModeWはそれぞれ、X/Y/Z軸においてテクスチャの範囲外の座標にアクセスした場合の挙動を示すものです。vk::SamplerAddressMode::eRepeatを指定した場合、ドラゴンクエストのマップのように範囲外にアクセスすると反対側の端に戻って繰り返します。
残りの引数の説明は割愛します。興味のある方は適宜調べてみましょう。
